To all whom it may concern:

Be it known that 1, WILLIAM H. OGDEN, a citizen of the United States,residing at Binghamton, in the county of Broome and State of New York,have invented a certain new and useful Improvement in Carbureters, ofwhich the following is a full, clear, and exact descri tion.

In the use 0 carburetors with internal combustion engines, especiallyengines of the high-speed, multi-cylinder type there is always more orless condensation of gasolene in the combustion chambers of thecylinders and in the intake manifold due to imperfect mixture of thegasolene with air; loss of power at high speeds and at low speeds underheavy load due to improper mixture and a consumption of gasolene all outof proportion to the power developed, and in the case of engines used inautomobiles and other vehicles to the distance traveled. l havefound\that by constructing a'carbureter in accordance with my inventionhere-'- inafter explained, the faults above men tioned are practicallyeliminated.

The object of this invention is to provide a carburetor which willinsure the complete vaporization of the gasolene and afl'ord a perfectmixture at all engine speeds and. under varying loads, thus eliminatingwaste 7 of fuel and insuring at all times maximum efliciency of theengine with which it .is

used, with a minimum consumption of gasolene. Although the carburetor ofthis invention is designed primarily for use with gasolene, it has beenfound to give very satisfactory results with the heavier hydrocarbons,suc as kerosene.

My invention contemplates the arrest in the carburetor itself of thefuel which has not entered into a homogeneous mixture with air by virtueof the physical phenomena of capillary attraction, viscosity, coho sionand adhesion, in such way'that the thusdetained liquid may besubsequently J subjected to mixture with air and be.uti] ized for supplyto the engine in efficient form,

without liability of its entering the intake or the engine cylinders inliquid form, as I will proceed now to explain and finally claim.

In the accompanying drawings illustratmg the invention,

Referring-to Figs. 1 to 8, inclusive, the carbureter has a body,portion. formed preferably of two parts 1 and 2, suitably securedtogether by screws 3 or bolts and nuts. The

) for the main and auxiliary air inlets 5 and 6, respectively, and havecircumferentially arranged channels which in conjunction with similarcomplementary channels in the communicatin with the sunken portion 15 inthe several figures of 'WlllCh. like parts are similarly designated,

part 1 form passages 13 and 14 respectively constant level by means of afloat 25 supported by an arm 26 which is dpivotally connected to an ear27 on the un bed 10, and this float is connected by a suit able link 28and lever 29 to a valve 30 sup ported by the lever 29 which is pivotedon an extension or arm 31 formed, on the shoulder 17 and this valve 30is operated by the float to open and close the gasolene port 32. Inplace of the valve and float arrangement here shown, any other approvedform may be used which will perform the proper functions.

11 air passage 33 extends from the main air inlet to the gasolenechamber 23 and opens into said chamber at a point below the level of thegasolene therein.

The bed 10 is formed on its upper face with a recess 34 concentric withthe gasolene chamber 23 and adapted to receive a bearing spider 35andhold it in axial alinement with the gasolene inlet 24. This 7 spiderhas a downwardly projecting exten- 'sion 36 which conforms to the shapeof the gasolene chamber '23 and extends into it thereby forming anannular passage 37 through which the gasolene must pass in reaching themixing chamber 38 of the car bureter. The upper face of the spider 35 isformed with an inverted conical ste 39 to receive the lower similarlyshaped earing end 40 of a spindle 41 upon which is mounted a rotorformed of a series or nest or any suitable number, preferably aplurality of disks 42 spaced apart by any as washers 43 and supported byand rning with the spindle.- The upper end of the spindle 41 is screwthreaded to receive a clamping nut 44 which holds the disks in pro errelation to each other and to the spin le, and the upper face of thisnut is provided with a conical bearing face 45 which fits a similarl andtrue revolution of the formed bearing 46 in the end of a sleeve 4 havingits upper end threaded into a neck 48 formed on or applied to the pa'rt1 of the body portion of the carbureter. By adjustment of this sleeve 47toward or away from the nut 44.the spindle and its assembled disks maybe made to .run in a tight or loose hearing, as desired. 'A bushing andbearing ring 49' is seated in the up per part 1 and is so arrang floatin its seat so as to insure the proper disks and to cause er side of theed as to partially needle valve seats in the gasolene inlet 24 and maybe adjusted to increase or diminish the supply by means of a hand wheel54 at the upper end of the valve. The adjusting screw portion 55 of theneedle valve is threaded into a sleeve 56 internally screwthreaded toreceive it and screwthreaded externally to coact witha complementalthread in the neck 48.. This sleeve has a laterally extending operatinarm 57 provided with a finger 58 whic engages the notches on a wheel 59fixed on the upper end of the stem of the needle valve, and this arm isconnected by a bell-crank lever 6.0 with an arm 61 adjustably mounted onan extension 62 of a. puppet valve 63 arranged in the auxiliary airintake 6, so that in case of high speed or heavy load of the engine andconsequent increased} suction, the auxiliary air inlet valve 63 will,through the arm 61, lever 60, arm 57, finger 58 and wheel 59, turn theneedle valve to increase the gasolene supply. The valve 63 may be ofordinary construction, and is here so.

shown, having. a stem 64 slidabl mounted in a bearing 65 and backed upand held normally closed by a spring 66. Referring particularlv'to Figs.5 and 6, the disks 42 are preferably circular and formed by stamping orotherwise, with centrally arranged vanes 67 bent. up at an angle fromthe plane of the disk and with stops 68 bent down wardly, for thepurpose when the disks are nested with the spacers 43 between them, ofpreventing the vanes from contacting with each other. Thus it will beseen that when the disks are nested or arranged in a series, one aboveanother, there will be a space between each disk and that one next3013081117 to it, caused by the spacers 43, and there will also be acorresponding space between theupper and lower faces of the vanes ofsuperposed disks caused by the stops 68. Each disk has acenter opening69 for the purpose of mounting it upon the spindle 41. The formation ofthe vanes 67 from the metal of the disk leaves a series of openings 70through which the vanes of disks below it may project; As -many of thesedisks may be used as the requirements of the size of engine andcorresponding size of carbureter demand. I

The lowermost disk 71 of the rotor or nest of disks, as shown in Fig. 7,differs from the others in'that it is imperforate and has no vanes andforms a seal over the bottom of the rotor, thereby causing all mixtureand gasolene to pass under the rotor to the chamber 38 and thence enterthe rotor between the disks at their peripheries.

Referring to Figs. 10 and 11, wherein a modification of the invention isshown by which it is adapted for use with known carbureters, only suchparts of the device of-the invention are used as are necessary toincorporate its principle. attachment is so made as to permit of theinstallation in known carbureters of the principle of the rotor formedof disks. To this end, there is a two-part .body portion having an upperpart 72 provided with an outlet 73 having the usual butterfly or otherthrottle valve and coupling flange (not shown), and a lower part 74:provided with an inlet 75 and coupling flange 76 for attachment to theflange of a carbureter, so as to conduct hydrocarbon mixture from thecarbureter to the device of the invention. The part 74 has a bed portion77 provided with a centrally arranged step 7 8 to receive a spindle 79upon which the disks 42 are mounted and held in position thereon by anut 80, these three last mentioned parts be ing similar to those alreadydescribed. The bearing face 81 of the nut 80 seats in an adjustablebearing post 82 threaded into a neck 83, its adjusted position beingmaintained by means of a lock nut 84. The bed portion 77. is providedwith a series of circumferentially arranged openings 85 so formed as toadmit mixture from the at tached carburetor with a whirling motion andtangentially to the disks, and the spacers 86 may be beveled,if desired,to offer as little resistance as possible to the upwardly fiowinmixture. A packing and bearing ring 8 is provided, as in the case of thecarbureter before described, to assure the easy and true revolution ofthe rotor and to prevent escape of mixture into the outlet by itspassing around and over the rotor, thereby insurin the escape of allmixture through the. aces between the vanes of the disks.

The main principle of the invention being embodied in both forms of thedevice shown and described, a' description of the operati'on of one formwill suflice for both.'

Referring to Figs. 1 to 9, inclusive, gasolene or other liquid fuel issupplied at 20 and through duct 19 and port 32 enters the float chamber22 and rises to a predetermined height therein and in the chamber 23which it enters through inlet 24. This height of the gasolene, orgasolene level as it is called, is kept constant by means of the float25, in the usual manner, and as described.

The suction in the carbureter caused by the engine to which it isattached, draws air- That is, the

in through air inlet 5 and passage 13 and this air enters the chamber 38tangentially owing to the circumferential arrangement of the passage 13,and moreover, it enters in a small current and with considerable forcedue to the constricted area of the opening 88 of passage 13 and forms awhirling current within the chamber 38. This current of air, in order toreach the outlet 7, must pass between the disks 42 and their vanes 67,and in so passing it imparts a rapid rotary motion to the rotor or nestof disks.

In addition to the current of air just described, an additional smalljet of air is sucked in through the inlet 33 and is introduced below thelevel of the gasolene in chamber 23, thereby forcing the gasolene out ofchamber 23 through annular passage 37 into chamber 38, where it issucked into the nest of disks. When the gasolene in thispartially'atomized form is brought in contact with the surfaces of thedisks, any portion of the liquid not homogeneously mixed with air butmerely held in suspension is deposited on the disks, and the capillaryattraction caused by adherence to the superposed adjacent faces of thedisks and the cohesion present in the particles of the gasolene causesthem to be arrested between the disks and form a thin film therebetween.The rapidly revolving disks will, by their centrifugal action, dischargea certain quantity of the accumulation of liquid gasolene from betweenthem and into chamber 38, where it will be again picked up by thewhirling current of air and re-introduced between the disks. These tion,capillary attraction and centrifugal force, together with a certainamount of viscosity present in the gasolene itself, make it impossiblefor much, if any, gasolene in liquid form to pass between the disks andtheir varies with the outrushing current of air. It will, therefore, be.evident that what gasolene passes between the disks and between theirvanes '67 to the outlet 7 must be very finely atomized and so mixed withair as to form a completely combustible mixture. The exhaust from anengine with which this carbureter was used was color-- which fact wouldtend to less and odorless, the belief that the vapor furnished by thecarbureter to the engine contained no free gasolene and was completelycombustible. This is also evidenced by lessened gasolene consumption.

, Under conditions of high engine speed or heavy load the auxiliary airvalves 63 will come into operation, thus admitting additional airthrough passage 14 in a whirling current as in the case of that admittedthrough the main air inlet 5.

The rapidity with which the gasolene may enter the chamber 23 isregulated by means of the needle valve 51. a

three forces, suc- The supporting arms 89 of the bearingspider 35 may bebeveled, as shown most clearly in Figs. 8 and 9, to offer the leastpossible resistance to the upwardly flowing whirling gasolene.
